Backorders/Out of stock Items - we have changed things so you can order things that are out of stock.

We accept orders for things that are out of stock. However we will not ship you order to you until we can send it to you all at once. We will hold on to you order until everything on it is available.

  • If you want something urgently only order it if it is in stock
  • If you want something that is out of stock then order it and we will add it to our next monthly order from VEX.
  • If you mix in stock items with out of stock items your order will be held until everything is in stock.
  • We will need payment even though the backorder has not been delivered.

Description

The light sensor uses a photocell that allows your robot to detect and react to light. With the light sensor, you can program a whole new range of capabilities to your robot. A Programming Kit is needed to change the program in the VEX Controller.

  • Analog input of light levels.
  • Usable range of 0 to 6 feet.
  • Find dark or bright areas.
  • Create more autonomous function.

 

Function:The light sensor enables a robot to detect light. Robots can be programmed to have a specific reaction if a certain amount of light is detected. The light sensor uses a cadmium sulfosolenide (CdS) photoconductive photocell. The CdS photocell is a photo resistor, meaning that its resistance value changes based on the amount of incident light.

Uses: Design a simple tracker that follows the beam of a flashlight, or use a light sensor to help your robot to avoid getting stuck under furniture by making it steer away from shadows. You can even give your robot color vision by putting colored filters on different light sensors!
